DE3208781A1 - Device for receiving and displaying boards, blocks or the like - Google Patents

Abstract

A device in the form of a bridge or a stand with a bearing arm (1) spans the region of the stored boards or blocks (2a and 2b), and the support table (3). The slides (4 and 5), which are mounted on the device and are displaceable horizontally in all directions, move jointly or individually over the piles (2a and 2b). The lifting units (6 and 7) are lowered and the clamping or suction units (10 and 11) move together to the width of the board. By clamping or suction, the board is lifted and conveyed transversely and the clamping or suction units move apart to the predetermined board spacing. The lowering and depositing onto the support table then take place at the desired board spacing. By means of the live rings mounted on the lifting units (6 and 7), the piles can be placed at any desired angle relative to the support table. <IMAGE>

Description

Device for picking up and laying out

of boards, blocks or the like The invention relates to a Device for picking up boards or blocks from one layer and laying them on with or without gaps on a frame, table or the like.

In many cases, including in pallet factories, those to be processed Boards or blocks placed in magazines by hand or directly on a frame or Table laid and distributed.

However, the automatic separation from magazines is then prone to failure. when the boards have curvatures. Placing and separating is by hand not prone to failure, but very time-consuming, especially when certain Gaps from board to board have to be observed. B. to 2 different board widths.

The invention is based on the object of creating a device which allows essentially all operations to be carried out in order to e.g. B. the Parts of a pallet or box before the nailing process or further processing put together.

This object is achieved according to the invention with a device such as it is characterized by claim 1.

Further developments of the invention are described in the subclaims.

The device of the invention is in the form of a bridge or a Stand with support arm, which covers the area in front of the machine Boards or blocks and the support table spanned.

The bridge takes one or more moving in all directions Slide on.

The slides are again subdivided into support arms with linear Lifting and clamping movements.

The individual movement processes and positioning can be carried out with standard drives in inching mode or via electronically controlled traversing, swivel and rotary drives be performed.

The invention is explained in more detail below with reference to the attached drawings explained. 1 shows a schematic side view of the device for Pick up U. $ Gi Laying out boards, blocks or the like in bridge design FIG. 2 shows a schematic end-side view. FIG. 3 shows a schematic side view the device for picking up and laying out boards, blocks or the like in 8-cylinder design with support arm.

The device according to the invention for picking up and laying out boards, Blocks and the like is designed according to Fig. 1 and Fig. 2 in the form of a bridge (1), which spans the storage areas of the wood (2a and 2b) and the lay-up area (3).

The wood storage bins (2a and 2b) can consist of one or more Stacking or storage areas consist of different wood cross-sections and lengths.

One or more slides move horizontally in the upper part of the bridge (1) (4 and 5), in which lifting units with slewing rings (6 and 7) move vertically. The turntables take on horizontally movable carriages (8 and 9) which at right angles to it horizontally the individual clamping or suction units Proceed with (10 and 11). The clamping or suction units are spring-loaded to avoid unevenness equalize in the board position.

The equipment with stand design and support arm (Fig. 3) spanned the wood storage area (2) and the lay-up area by rotating the stand (1).

The workflow is as follows: On the wood storage areas (2a and 2b) Fig. 1 are two stacks, one with wide goods (2a), one with narrow goods (2 B).

The width of the stack is expedient to choose so that the on the Laying place (3) boards to be laid one, two or three times the number of boards result in the stacking area.

The carriages (4 and 5) move together or separately over the Stack (2a and 2b). The lifting units (6 and 7) lower onto the stacks (2a and 2b), the clamps or suction units (10 and 11) move onto the slide (8 and 9) to the specified board width together so that they each grasp them in the middle can.

Clamp or suction units that need to be lifted because of the specified Board numbers are not required, remain in the edge zones of the carriage (8 and 9).

The boards are individually clamped or sucked in at the end and lifted by the lifting units (6 and 7). After the carriage has been transported (4 and 5) the clamping and suction units (10 and 11) are moved apart to the desired board spacing. After lowering the lifting units onto the lay-up area (3) the boards are released and the new operation is repeated, whereby the carriages (4 and 5) offset above the stack (2a and 2b) come to stand to pick up the nearest boards.

If board layers are to be formed according to No. 12 Fig. 2 with unequal board widths, then takes place after the clamping and suction units (10 and 11) move apart the sliding of the carriages (a and 9) into one another at the specified distances, d. H., As can be seen in Fig. 1, slide (8) moves to the right, slide (9) to the left.

As the boards move into one another, they are flush or flush with the front be stored offset.

Thanks to the slewing rings attached to the lifting units (6 and 7) the stack is at any angle to the storage area.

Claims (8)

Claims: 1. Device for picking up and laying out boards, Blocks or the like, not shown by a bridge (1) or Stand with support arm on which one or more carriages with lifting units (4, 5, 6, 7) are arranged vertically and laterally, as well as rotatable and / or pivotable. 2. Apparatus according to claim 1 characterized g e k e n n -z e i c h n e t, da3 the lifting units (6 and 7) accommodate horizontally movable carriages (8 and 9), on those in the right angle several clamping and / or suction units horizontally Proceed with (10 and 11). 3. Apparatus according to claim 1 or 2 characterized g e k e n n -z e i Note that the clamping and / or suction units (10 around 11) are resiliently mounted to compensate for unevenness in the board layer. 4. Device according to claims 1-3, thereby g e k e n n -z e i c h n e t that the slide and lifting units (4, 6, 8) with their clamping and / or singing units (10) in inching mode, after electronic preselection control or mechanical grid position can be moved in such a way that they take up boards or parts lying next to one another and can put them down at predetermined intervals. 5.
